Red shift and blue shift are an illusion of movement.
They are in a gravity well.
Resisting the expansion of the universe.
Why do spiral galaxies exist?
I will show you. For 200 years geologists measured the age of rocks of the earth.
So how old since the rock formed.
So what happens if you do an animation that merely removes the rock by age? You see that the earth appears to be expanding but not changing size.
How does this relate to galaxies?
Well consider the earth and gravity and elements that are lighter will go up in the gravity well and heavier elements will go down.
So then that is the motive force and so specific density.
"Specific density is the ratio of the mass versus the volume of a material. "
So you see layers of atmosphere then water and etc.
So the atoms migrate.
So then you can see that here but first turn off the volume. Do not be distracted by the guy who made the animation for me. He does not understand physics.
Turn off the volume.
Turn it off and watch the animation only.
